At Techdirt we're no strangers to people disagreeing — often, let's say, vehemently — with our views on copyright. But I've still often been surprised by how angry some people get about the simple, factual observation that copying is not theft. We've made the point many times (and it remains true even if you think copyright infringement is a dastardly crime), and a few years ago we put it on a t-shirt and some other products via the print-on-demand platform Teespring, where we sell a bunch of gear. But you won't find the shirt at those links anymore, because last week we received notice from Teespring that it had been taken down... supposedly for copyright infringement.

At first, it seemed like this was likely a simple error from an automated system (the takedown notification explained that it was not based on a complaint from a third party) and I suspected we had been caught up in Teespring's response to an unrelated (and amusing) phenomenon that was taking place at the same time: a bunch of artists and others online were aiming to prove that there are bots out there copying artwork from social media and selling it on print-on-demand sites, by spreading funny and extremely-infringing images which did, indeed, show up on several print-on-demand t-shirts soon afterwards.
